Slinger

[Phoenician]

Make sure there's a half inch from the neck hole that you sew back to the shoulders. Double sewn, because this corner is the weak spot of the whole garment. On my tunic, I then rolled the cut edges at the shoulder (both sides of the neckhole) under and sewed over the fold, capturing the cut edges underneath. With finer weave cloth, that would not have been necessary.

Did not quite understand the quoted part, but I understood everything else. I am not sure what you mean sewing half an inch back to the shoulders, and I assume by double sewn you mean sew two lines of stitching.

I have washed and dried the first piece of fabric (the natural color) and everything worked, both the first blanket stitch I was using and the much quicker whip stitch held up fine.
I did iron the fabric, but I lack an ironing board, and I had to lay a couple of towels on the table to protect it. This made the surface somewhat uneven. The fabric being nine feet by five feet also meant I had to do very small areas at a time. I ironed the entire piece, but I don't know if those factors will cause any problems.
